If you can get into some of these, you can
have some great fishing because they are carefully managed to ensure a
good fishery. These include many sites from farm ponds to lakes like
McBride. Then, there are the big natural lakes like Miccosukee and big
man-made lakes like Talquin, both of which have had bass fisheries
that are hard to beat in the past.
If there seems to be something missing at this
point, it’s because Lake Jackson has not been mentioned. This lake
has got to be one of the very best that has ever existed. If it’s
not, I’d like to find those that are.
The numbers of huge bass caught in Lake
Jackson in the 1960s and 1970s are almost unbelievable. One of the
main reasons that the lake has been so productive is because of the
periodic natural draw-down. This is a locally known phenomenon of the
lake’s water disappearing into an opened sink hole about every 25
years, then returning at some unpredictable time that has been
recorded to be from a few months to several years.
A commonly used fisheries management tool is
the man-induced draw-down of lakes and ponds. Most of the time this is
not feasible on large natural systems. But, Lake Jackson is fortunate
to have mother nature handle this task. The de-watering of a lake
allows for rapid oxidation of accumulated organic matter on the lake’s
bottom and the growth of terrestrial vegetation, both of which
contribute to an improved fishery upon the return of the water. The
build-up of organic substrate results from the continual sloughing of
aquatic plant material and the inflow of contaminated run-off. The
oxidation or physical removal of this material helps the fish by
eliminating this source of oxygen depletion and re-establishing the
sandy spawning areas required by Centrarchids (the Sunfishes i.e.bream
and bass). The growth of terrestrial vegetation provides a nutrient
source that is released into the water column when the lake refills
and kills the terrestrial plants that cannot tolerate inundation.
Those nutrients are the basis of the food chain that begins with the
plankton that feed on them.
Immediately following the disappearance of
Lake Jackson’s water in September of 1999, local government agencies
cooperated to implement a plan to help restore the lake by physically
removing the huge quantities of muck that had accumulated as a result
of surrounding development, particularly the construction of I-10 and
the Tallahassee Mall. More than $8 million was spent on this project
that paid for trucks to haul millions of cubic yards of this sediment
from the bottom of the lake.
The water has now returned, so the natural
draw-down lasted almost two years this time. I recently asked the
state geologists about the expected fate of the lake following its
refilling from the heavy rains from the season’s first two tropical
storms. They said that the hole is still open and draining, but they
expect the lake to remain filled until the next major drought. They
contend that the open Porter Sink drains 15 million gallons of water
per day, and the normal daily inflow from average rainfall in the
surrounding watershed far exceeds that amount.
I also called the Assistant Director of
Freshwater Fisheries of the Florida Fish and Wildlife Conservation
Commission (FWC) to find out their plans for re-stocking the lake and
managing it in the future. At this point there is no plan to re-stock
the lake, but that may be the best scenario in the long run for a
healthy fishery. Why? Because of Lake Jackson’s unique ability to
produce many huge fish, it is probably best to not dilute that unique
gene pool through stocking. Spawning was observed this past spring in
the pools that remained throughout the drought. So, natural
recruitment will occur rapidly.
The only remaining issue to be addressed to
ensure another magnificent fishery in Lake Jackson in the near future
is the regulation of fish harvesting. Unfortunately, after spending
all that money to remove the muck, the main ingredient for a good
fishery may again be ignored. The absolute most important factor to
ensure a good fishery is to not take the fish out of the system,
whether salt or fresh water. In addition to that being obvious through
common sense analysis, the scientific data have proven it time and
time again. Additionally, there is other proof such as the highly
lauded fishery at places like Bienville Plantation where there is no
allowed harvest of largemouth bass.
Upon discussion of this issue with the FWC
staff, they indicated that agency management is receptive to
establishing a catch-and-release management policy for Lake Jackson,
but they will never do such a thing without strong public support. The
reason is that the traditional fisherman does not understand the
scientific or the common sense reasoning for a catch-and- release
fishery, or he/she is selfishly apathetic and wants to just get what
they can while they can. That is the mentality that must be altered if
we are going to have any quality of life on a planet with 6 billion
people and a rapidly increasing population. So, let the FWC know that
you support a catch-and-release fishery for Lake Jackson so that there
will be fishing in Lake Jackson’s future like there was before it
was destroyed through legal over-harvesting.
